ROBERT F. GOLDEN, OF SOUTH ORANGE, NEVI JERSEY, ASSIGNOR TO THE NATIONALLOCK WASHER COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CURTAIN FIXTURE.

To all whom it may concern:

Be it known that 1, ROBERT F. GOLDEN, a citizen of the United States,residing at South Orange, county of Essex, State of New Jersey, haveinvented certain new and useful Improvements in Curtain Fixtures; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains, to make and use the same.

This invention relates to curtain fixtures, in which a spring tensionroller is employed at the top and constantly tends to wind the curtain,the latter being equipped at the bottom with what are known as curtainrods that are provided at their inner ends with finger pieces which arepinched toward each other to draw the rods inwardly against theresiliency of springs that surround them, these rods being usuallyconnected at their outer ends to cams that are carried by heads thattrack in grooves at the sides of the window casing.

This style of curtain fixture is well known and is commonly used on thecurtains of railway car windows, and the present invention has referencesolely to the rods and the cams that are carried by the trackin heads.

Referring to the accompanying drawings Figure 1 is a front elevation ofthe ourtain fixture as it appears when properly engaged with the sidegrooves of the casing, one end portion being shown in section.

Figure 2 is a broken section at right angles to that shown at Figure 1,and

Figure 3 is a detail broken perspective view of the outer end of the rodshowing a modification thereof.

Similar numerals of reference denote like parts in the several figuresof the drawing.

In curtain fixtures of this description it has heretofore been thepractice to connect the outer end of each rod with its cam so that whenthe rod was pinched inwardly it would withdraw the cam.

According to the present invention, there is no connection whateverbetween the rod and cam, and when the rod is drawn in wardly it does notwithdraw the cam with it.

As there are two rods, one for each end of the fixture, and as theserods are identical in form and function, only one of such rods will bedescribed.

1 is the tube that is secured to the bottom of the curtain, 2 the fingerpiece and 3 the rod surrounded by a confined spring 4, all constructedand assembled as heretofore.

To the outer end of the tube is screwed the shank 5 of the head 6 whichlatter at its ends has the usual track rolls 7 that travel in the usualgroove in the window casing.

The outer end of the rod 3 is formed into a laterally extending portion8, which engages between the sides of the head 6 so as to prevent theindependent rotary movement of the rod. As shown at Figure 1 this part 8is in the form of a hook merely because this is a very cheap way ofproviding a laterally extending portion and not because any function isto be performed characteristic of a hook, and the end of the rod may beflattened so as to provide a laterally extending part 9 as is shown atFigure 3. In both instances the laterally extending portion providesmeans cooperating with the head for preventing the independent rotationof the rod, and in this connection attention is called to the fact thata cross-pin through the end of the rod or mere side fins formed thereonare fully within the scope of this invention, the gist of which rests inthe broad idea of so equipping the outer end portion of the rod that itwill only be revolved by rotation of the head and yet will have noactual connection whatever with either the head or the cam 10 whichlatter is pivoted at its lower end within the head.

In assembling the structure, the rod is inserted within the tube and thehead placed over the rod so that the portion 8 is located between thesides of the head, and the latter is then revolved so as to cause theshank 5 to screw on to the rod and at the same time cause the inner endof the rod to screw within the threaded socket 11 of the finger piece 2.

The portion 8 will always be normally projected against the cam 9 toforce the latter beyond the head into frictional contact with the track,but when this rod is withdrawn by manipulation of the part 2, the cam nolonger is backed by any force whatever and will therefore readily yieldto permit the ready operation of the curtain.

This assembly of the rod free of any connection whatever at its outerend does not impair the efficiency of the fixture in the least, but itdoes enable the fixture to be furnished at considerable less cost thanheretofore since many operations are dispensed With, taking intoconsideration that there 5 are two rods to a fixture.

What is claimed is In a curtain fixture of the character described, thecombination With the tube, the central fingerpiece socket, the headthreaded 10 on the tube, and thggarn Within said head,

of the resiliently acting rod threaded at its inner end Within saidsocket and having at its outer end a laterally extended portion that isfreely housed between the sides of the head, is rotated by the rotarymovements of said head, and is normally projected against said cam.

In testimony whereof I affix my signature hereto.

ROBERT F. GOLDEN.
